ROOFING-SHEET.

SPECIFICATION forming part of Letters Patent No. 407,195, dated July 16,1889.

Application filed April 10, 1889- Serial No. 306,685- (No model.)

To [LZZ whom it may concern:

Be it known that I, CHARLES M. GAERIsoN, a citizen of the United States,residing at \Vichita, in the county of Sedgwick and State of Kansas,have invented certain new and useful Improvements in Roofing-Sheets; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention has relation to a roofingsheet, and is designed as animprovement upon the invention described in the Letters Patent grantedto me October it, 1888, No. 391,237.

The novelty will be fully understood from the following description andclaims, taken in connection with the annexed drawings, in which Figure 1is a perspective view of a rootingsheetpreparedaccording to myimprovements with a portion of the flexible cement removed to expose theinterposed wire fabric. Fig. 2 is a cross-sectional view of the same,and Fig. 3 is a plan view of a sheet of the wire fabric before beingsubjected to the action of the machine by which the flexible cement isapplied.

In carrying out my invention I take a strip of woven wire with asufficiently close mesh and place it upon a roll mounted in a frameholding the composition of matter with which it is coated. Thiscomposition of matter, as set forth in my Letters Patent above referredto, is composed of asphaltum, coal-tar, sand, and animal-hair in certainproportions. The

full and level surface.

under side of this sheet of woven Wire bearing the composition a sheetof tarred paper or tarred cotton cloth 13. This tarred sheet issometimes known as tarred felt, and may be used in double or single ply.

\Vhen two-ply tarred paperis used, one ply is to be coated withasphaltum or pitch, the same as the wire. In preparing this tar-redpaper or tarred cotton cloth it may be passed through the same machineas the one in which the wirecloth is prepared, being drawn from one rollto another, and in its passage subjected to the composition. Aroofing-sheet prepared in this manner I have found to possess thequalities of being both fire and Water proof, and by the use of the wirein combination with the tarred sheet the roofing-sheet can be preservedindefinitely and used in any climate, possessing flexibility and beingconveniently handled.

Having described my invention, what I claim is- 1, As an improvedarticle of manufacture, a flexible water and tire proof fabric composedof a sheet of woven metallic Wire having incorporated with it a flexiblecement composed of asphaltum. coal-tar, sand, and animal-hair, and atarred sheet of paper, cotton cloth, or tarred felt arranged on the un-CHARLES M.
